Cyosurgery in curing cancer

                                                                                         

Modern medicine has many new, inovative techniques of dealing with the
tough diseases that attack our body, most of them still at the
beginning or in research. One of these methods that has a good potential is
cryosurgery.

Cryosurgery has resulted from studies in cryobiology, and it involves
the use of extremely low temperatures to disturb abnormal or diseased
tissue. In other words, cryosurgery is a method for killing infected
cells and tissue by freezing them.

Cryosurgery has a great potential in treating different forms of
cancer. It can treat both external tumors (skin tumors) by spraying liquid
nitrogen on them, and internal tumors, case in which the liquid nitrogen
in carried inside the body through an instrument called cryoprobe,
which is in direct contact with the tumor. The cryoprobe is inserted in the
body through a small orifice, and in order not to damage the nearby
healthy cells, it is guided through the body straight to the destination
with the help of ultrasounds. Then, the diseased cells freeze and die.
After they defrost they are absorbed by the body.

These methods of cryosurgery can be used in the treatment of many types
of cancer, from which the most important are those that affect the
liver and the prostate. Other types that can be treated with cryosurgery
are some forms of skin cancer and bone cancer, but in early or
precancerous stages, because in further stages the disease spreads through the
entire body.

It must also be known that cryosurgery has a few side effects. They are
not too severe, but pain, scars, cramps, swelling or the loss of some
sensations can occur. These effect are still being studied.

Cryosurgery is still being researched, and it seems to be better that
other alternative methods of treating cancer, and with less side -
effects and complications. It is also cheaper than some methods, but it has
one disadvantage - because it is a relatively new method its long -
term effects can not be determined yet.

So, we can only hope that cryosurgery will improve in the nearby future
and it will help in the saving of people's lives.
